The Factory Design Pattern in C++: A Comprehensive Guide with Example
Introduction In software development, the Factory pattern is a creational design pattern that provides an interface for creating objects without specifying their exact class. This pattern allows the client code to create objects based on certain conditions, encapsulating the object creation process and promoting loose coupling between the client and the concrete classes. In this blog post, we will explore the Factory pattern and provide a detailed C++ example to illustrate its implementation. Understanding the Factory Pattern The Factory pattern follows the concept of "separation of concerns" by providing a separate factory class responsible for object creation. It enables the client to interact with the factory to obtain objects, without having to know the specific class being instantiated. Key components of the Factory pattern: Abstract Product: Interface representing the product classes. Concrete Products: Classes that implement the Abstract Product interface. ...
